From https://en.wikipedia.org/wiki/BMP_file_format#Pixel_format:
"The 1-bit per pixel (1bpp) format supports 2 distinct colors, (for
example: black and white). The pixel values are stored in each bit, with
the first (left-most) pixel in the most-significant bit of the first
byte.[5] Each bit is an index into a table of 2 colors. An unset bit
will refer to the first color table entry, and a set bit will refer to
the last (second) color table entry."
I don't know whether this Wikipedia article has a lot of authority
really, but please note the "for example black and white".

From
https://msdn.microsoft.com/en-us/library/windows/desktop/dd318229%28v=vs.85%29.aspx:
"If biCompression equals BI_RGB and the bitmap uses 8 bpp or less, the
bitmap has a color table immediatelly following the BITMAPINFOHEADER
structure. The color table consists of an array of RGBQUAD values. The
size of the array is given by the biClrUsed member. If biClrUsed is
zero, the array contains the maximum number of colors for the given
bitdepth; that is, 2^biBitCount colors."
Nothing about "monochrome" here.
